Harvesting finger limes: A thorny affairToday, Shanley Farms grows two finger lime varieties sold under the company’s trademarked Citriburst brand. Beyond their distinctive appearance, finger limes have attracted attention for their potential health benefits. “[Finger limes have] lots of vitamin C, A, E, and B12, as well as organic essential oil compounds. One finger lime has three times the amount of vitamin C as a mandarin.” Finger lime trees carry dense thorns, requiring workers to harvest by hand while wearing protective gear.
